This is simultaneously one of Saul’s greatest offenses against God and one of the times when he is a sympathetic character. As he comes to battle the Philistines, he has been cut off from any contact with God. It must seem as though everyone conspires against him, that he is all alone in the world; so, against his own decree forbidding such a thing, he consults a medium who can speak to the dead, a dark practice according to Hebrew law.
